The HTML markup produced by this template includes an hCard microformat, which makes the person's details parsable by computers, either acting automatically to catalogue articles across Wikipedia or via a browser tool operated by a reader, to (for example) add the subject to an address book. For more information about the use of microformats on Wikipedia, please see the microformat project.

Date-of-birth ("bday") parameters will only be included in the microformat if {{Birth date}} or {{Birth date and age}} are used in the infobox.
